How to Display a Tkinter Application in Fullscreen on macOS?
Tkinter is a Python GUI toolkit that allows developers to create desktop applications with graphical user interfaces. One common challenge that developers face is how to display their Tkinter application in fullscreen on macOS. This article will show you how to do it in a few simple steps.
Step 1: Importing the Required Libraries
Firstly, we need to import the necessary libraries. In this example, we’re importing the Tkinter library and setting up a basic GUI.
import tkinter as tk
root = tk.Tk()
root.geometry("400x300")
Step 2: Creating a Function to Display the Application in Fullscreen
The next step is to create a function to display the application in fullscreen. We can do this by adding the following function to our code.
def toggle_fullscreen(event=None):
root.attributes("-fullscreen",
not root.attributes("-fullscreen"))
return "break"
In this code, we’re creating a function called toggle_fullscreen
that toggles the fullscreen mode of the application. The event=None
parameter allows the function to be triggered either by the user clicking a button or by pressing a key on the keyboard.
Step 3: Triggering the Fullscreen Function
The final step is to bind the toggle_fullscreen
function to a button or key. In this example, we’re going to use the Escape
key to toggle fullscreen mode.
root.bind("<Escape>", toggle_fullscreen)
Now, when the user presses the Escape
key, the toggle_fullscreen
function will be called, and the application will switch between fullscreen and windowed mode.
Complete Example
Here’s the complete code for a basic Tkinter application that can be displayed in fullscreen mode.
import tkinter as tk
root = tk.Tk()
root.geometry("400x300")
def toggle_fullscreen(event=None):
root.attributes("-fullscreen",
not root.attributes("-fullscreen"))
return "break"
root.bind("<Escape>", toggle_fullscreen)
root.mainloop()
Conclusion
In conclusion, displaying a Tkinter application in fullscreen on macOS is a straightforward process. By creating a function to toggle fullscreen mode and binding it to a key or button, you can provide your users with a seamless fullscreen experience. With this knowledge, you can create more immersive and engaging desktop applications using Tkinter.
